With the rise of the third generation mobile communication technology, the commercial use of 3G is imminent. In the early stage of network construction, network planning is particularly important. For operators, in order to improve ARPU (Average Revenue Per User) from customer satisfaction, early network planning is a key competitive factor. Globally, people are intensively developing and researching new planning tools and calculation methods. As one of the three major standards, WCDMA has begun to be commercialized in some countries and regions in Europe and Asia, and has achieved good results. WCDMA is fundamentally different from traditional GSM networks, which puts forward higher requirements for network planning. The quality of planning will directly affect network performance and construction costs. This article aims to explain the characteristics and steps of WCDMA network planning. I. Key features of WCDMA wireless network planning 1. Power control is the key 2. Business model-oriented 3. Asymmetric uplink and downlink 4. Soft switching is different from the switching method of GSM II. WCDMA network planning procedures 1. Coverage and capacity planning 2. Link budget 3. System simulation 4. System optimization
